We evaluated a commercially available radioimmunoassay technique for detecting the soluble antigen of Legionella pneumophila serogroup 1 using concentrated and nonconcentrated urine. Concentration was achieved by selective ultrafiltration. The sensitivity of the technique was 60.9% for nonconcentrated urine and 80.4% for concentrated samples, with 100% specificity in both cases.
我们评估了一种市售的放射免疫测定技术,该技术使用浓缩和未浓缩的尿液来检测嗜肺军团菌血清1型的可溶性抗原。通过选择性超滤实现浓缩。该技术对未浓缩尿液的敏感性为60.9%,对浓缩样本的敏感性为80.4%,两种情况下的特异性均为100%。
